compatibility should be OK, for the performance, hard to say without any benchmark BUT from various site have seen very encouraging OpenCL performance, even better than 290X cards... so go with 980.....

Any news on the GTX 980 card Here at work we are planing to buy new graphic cards but they had planed for GTX 780, so Im really interested to know if I should try convincing them to buy the 980 card or if it really is worth the money going for the 980 instead of 780.

Actually, I just found out that one guy here at work today installed 980 card, will try that with agisoft asap. What is it that I should look for to really know that agisoft supports it? Is it that the gpu kicks in when calculating dense clouds?
